Abstract: Disclosed are a method and an apparatus for optimizing a data route in a mobile communication system. A method of setting an internet protocol (IP) session in a mobile communication system, by a Mobile Station (MS) includes querying and obtaining an IP address of a corresponding node corresponding to a predetermined application and an IP address of a corresponding gateway corresponding to the corresponding node. The method also includes accessing the corresponding gateway based on the IP address of the corresponding gateway. The method further includes receiving a corresponding gateway allocation IP address from the corresponding gateway and forming a tunnel between the MS and the corresponding gateway. The method includes setting an IP session between the MS and the corresponding node based on the IP address of the corresponding node and the corresponding gateway allocation IP address.

Abstract: A method for creating a unique and secure mobile internet protocol version 4 connection for a packet data network is provided. The method includes generating an extended master session key to create a mobile internet protocol root key. The method also includes creating a mobile internet protocol security parameter index based on the mobile internet protocol root key and an access point name. The method further includes deriving a mobile node home agent key based on the access point name. Furthermore the method includes associating the derived mobile node home agent key to the created security parameter index. Moreover the method includes providing the unique and secure mobile internet protocol version 4 connection to transfer data for the packet data network connectivity.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention relates to a method and apparatus for anchoring of a terminal in a wireless communication system. The method for anchoring the terminal in the wireless communication system may include receiving attribute information indicating whether at least one gateway operating as an anchor for at least one default Packet Data Network (PDN) connection supports session persistence, detecting a new flow generated by an application, determining whether a further PDN connection is required for the flow on the basis of the attribute information indicating whether at least one gateway supports session persistence, and if no further PDN connection is required for the flow, using an Internet Protocol (IP) address allocated by the at least one gateway as a source IP address of the flow.
